The present application is a divisional application of our copending application Ser. No. 16,259, filed April 13, 1935, which relates to new, valuable, condensation products which are suitable as said water-solubilizing step may be as desired.

In other words, the entire process consists in acting on the said organic initial material containing at least one hydroxy group in any deassistants for the textile and related industries, sired order with two diii'erent compounds, namely 5 and a process of producing same. a compound capable of reacting as an alkylene We have found that valuable, water-soluble oxide free from other oxygen than the oxide (which term includes colloidally soluble) conoxygen and containing at least three carbon densation products can be obtained by reacting atoms in the molecule and with a compound 10 an organic compound containing at least one capable of reacting as alow molecular polyhydric 10 hydroxy group in the molecule, with a compound alcohol containing one hydroxy] group per each capable of acting as an alkylene oxide free from carbon atom or, speaking in greater detail, the other oxygen than the oxide oxygen and concompounds containing hydroxy groups may be taining at least three carbon atoms in the molefirst reacted with alkylene oxides containing at cule, and effecting a water-solubilizing step. least three carbon atoms and then with poly- 15 The term compound capable of reacting as an hydric alcohols of low molecular weight or the alkylene oxide free from other oxygen than the procedure may be reversed by first causing the oxide oxygen and containing at least three carpolyhydric alcohols of low molecular weight to bon atoms in the molecule comprises alkylene react with the compounds containing hydroxy oxides with the said number of carbon atoms groups, the resulting condensation products 20 themselves, furthermore 1.2-propylene glycol and thereupon being reacted with the alkylene oxides its higher homologues. containing at least three carbon atoms in the Suitable initial materials containing hydroxyl molecule.

The said alcohols may atoms, preferably several molecular proportions also contain substituents, such as, for example, of the latter (for example of propylene oxide) halogen atoms, nitro or sulphonic groups. are used for each molecular proportion of the The water-solub l zin step which is to be apinitial material.

In many cases it is advantageous to cause The condensation with the compounds capable several of the said compounds to enter into reof reacting as polyhydric alcohols of low molecaction, preferably in several stages. ular weight is also advantageously carried out If the said preferred form of effecting the in the presence of the said condensing agents 50 water-solubilizing step is employed the sequence at elevated temperature and it is also preferof the condensation with the compound capable able to work under increased pressure. of reacting as an alkylene oxide free from other If compounds containing at least one hydroxy oxygen than the oxide oxygen and containing at group are employed as are high molecular (which least 3 carbon atoms in the molecule and the contain at least 6, preferably at least 8, advantageously from 8 to 18 carbon atoms per molecule) the water-solubilizing step may consist in a sulphonation; this is eil'ected in the usual manner by treating the products with sulphuric acid, oleum, sulphur trioxide or chlorsulphonic acid, if desired in the presence of solvents or diluents or while adding compounds capable of withdrawing water.

The products obtainable according to the present invention are suitable, for example, as wetting, washing, dispersing, levelling, softening and like agents in the textile, leather, paper, lacquer, rubber and like industries; they are also capable of employment with advantage in the cosmetic and pharmaceutical industries in many cases. They have in particular a high protective colloid action and, for example, prevent to a great extent the separation of calcium soaps when working with soaps in hard water. Many oi the products are also suitable as superiatting agents for soaps. The products may be advantageously employed together with other substances usually employed in the textile, leather, paper and like industries, for example, with soaps, Turkey red oils, true aliphatic sulphonic acids of high molecular weight, alkylated aromatic sulphonic acids, organic solvents, such as cyclohexanol, cyclohexanone, benzyl alcohol and carbon tetrachloride, or salts, such as Glaubers salt, alkali metal phosphates, waterglass and borates. They may also be employed together with oxidizing .and reducing agents, such as sodium hypochlcrite and sodium hydrosulphite, or with vegetable mucilages, glue, starch or ethylene oxide polymerization products. The following examples will further illustrate the nature of this invention, but the invention is not restricted to these examples. The parts are by weight,

Example 1 1 molecular proportion'oi cetyl alcohol is condensed with 6 molecular proportions of propylene oxide and subsequently with 2 molecular proportions of ethylene oxide at about 140' C. under pressure. 1 molecular proportion 01' the product obtained is dissolved in 10 times its weight of carbon tetrachloride and then 1 molecular proportion of chlorsulphonic acid is allowed to flow into the solution at a temperature below 10 C. As soon as a sample withdrawn is soluble in water, the whole is poured into icewater, the ether evaporated oil and the aqueous solution neutralized with alkali or organic amines. The solution thus obtained may be directly employed for washing loose wool. By evaporating the neutral solution, a good washing agent is obtained in a solid form.

A satisfactory washing agent is also obtained if cetyl alcohol is condensed under the said con ditions with 4 molecular proportions of propylene oxide (not with ethylene oxide), sulphonation and working up being carried out in the manner indicated above.

Example 2 From about 16 to 20 molecular proportions of ethylene oxide are caused to react in a stirring vessel at 140 C. in the presence of 0.5 per cent of caustic soda solution 0140 B. strength with 1 molecular proportion oi the water-insoluble condensation product from 1 molecular proportion of cetyl alcohol and 4 molecular proportions of propylene oxide (the preparation of which condensation product is described at the beginning of Example 1). The wax-like reaction product has a good solubility in water and is an excellent protective colloid since it prevents the precipitation of calcium soaps in hard water; furthermore the product has a good equalizlng action in vat-dyeing.

l'namplc 3 2 molecular proportions of propylene oxide are caused to react with 1 molecular proportion of dodecyl alcohol. 1 per cent of caustic soda or dimethylaniline is added to the reaction product obtained and from 4 to 8 molecular proportions ct ethylene oxide are reacted therewith in a pressure-vessel. The resulting product is a very suitable addition in the preparation of pastes, creams and the like by means of vaseline, soi't paraflin wax, paraflin oil, wool fat and the like.
